Leiters Patent No. 96,264, dated October 26, 1869.

IMPROYED SUGAR AND lSORGHU'M-Ml'lhl'a.

Ille Schedule referred to in than Letten Patent and making part of the camo To all whom "it may concern Beit known thatwe, D. J. PoWERs and HENRY making part oi' this'jspecification- Figure 1 beinga plan'ot* the mill;

Figure 2, a side elevation thereof, together with tlrelcarrier which conveys the pressed stalks ti'om the. m,

gigio-e 3, a vside view of the castironbed of pthe ml -Figurc 4, a top view-of the same', and

Figure 5, a transi'eisc section ofthe three pressureroillers in their relative positions, as mounted in the Inl Like vletters designate corresponding parts in all of theiigures.

We cast the bedA., on which the working-parts are to be mounted, in one piece, of such ashape as to furnish fixed oblique bearings n n, for ythe two 4lower pressure-rollers, and to form a rcceptacle,'w, to hold the juice as itis expressed by the rollers, and from which to draw at convenience. This construction subservcs economy, compactness,. `st`rength, and conven1enoe. f

'The dxivingshatt of the milialso may have its bearings in the bed, below-its receptacle rw, or it may pass entirely under the bed.

This drivingshaft B extendsthrough or under the bed,'so that it may gear, at one side .of the mill, with one oty the lower pressure-rollers, and at the other side of the mill, with `the other of these pressure'- rollers.

Thus, at one side, a pinion, F, on the driving-shaft, gears into a cog-wheel, G, on .the shaft d ,of the pressnre-roller D, and at the other side, apinion, H, on the driving-shait-B, gears intov a cog-wheel, I, entire shaft f of the pressure-roller E.

Two purpose-sare gained by this methodof gear- Inr:

When a single pinion is employed to drive both of lir'st, by thus driving the two pressure-rollers, yeach I the lower pressure-rollers, there is 'necessarily a considcrable space between these rollers, so that their. cogiwheeis shall-not come in contact witheach other, and thus there is a great liability ot' the stalks going` down betweenthese rollers. This trouble is obviated by our arrangement.

Thenpper roller G is driven by the cog-wheel G on the shaft f one of the lower rollers, gearing into a pinion, J, iig. 2, on its shaft j and, if desired, there may be a similar pinion on the othery end of its shaft, receiving power from the cog-wheel I of the other' .loWerrollerL The bearings k k, in which the journals ofthe upper roller turn, fit loosely in their seats-M M, sothat the roller can have suicicnt play to adapt' itself to the lower rollers, according to the pressure exerted by either, and equalize their action.

.Tile strap-bolts L L passing over these bearings, and having thev India-rubber blocks or washersl l at thelr-lower'ends,allow this -freemovementof the' upper roller at the same time that Strong pressure is exerted.

The nuts nl' m adjust the amount ot pressure and space between the .rollers.j

The endless-belt carrierN is mounted in a'frame, pp, which is hinged, by the lower shaft of the be'lt, in

standards ofthe main frame' ofthe inill.

f There is a pinion, o, on'this shaft, into .which an intermediate pinion, n, gears, as well as into one ot' the roller cog-wheels, as G, and receives and 'transmits the motion to the carrier.

This positive gearing from rthe mill, and applied to the carrier, atthe common centre of its attachment to the-frame Q .i11e-'niill, and -On which the carrierfiame turns, is an excellent arrangement, simple, effective, andnot liable to any disarrangement.

1t is valso'as compact as possible; and, what is of essential importance, the lowerend of the endless belt is'brought into close proximityto the rear lower roller D,and in such relative position thereto as properly and without fail to receive the bagasse as it comes ti'om the rollers.-

-We employ an improved arrangement for tighten- 'ing the endless belt and proportioning the tension to the weight of the stalks conveyed.- It is by means ot' a siioe, I in which the upper roller s Vofthe endless Vbelt is mounted, and which. has a siidingf movement insiots -r r of the frame p.

. lien the supporting-legs q are pivote-d to this shoe, and when the carrier. is supported thereby, as indicated in fig. 2, the weight of the'i-.carl-ier, 'pressing' on the legs, `slides the shoe l upward till the belt N vis tightened. This arrangement is entirely self-acting, and is very s iniple, convenient, andetfective.

What we claim as our invention, and desire to sc cure v'by Letters Puten t, is

l. The combination :ind arragementof the driving-shnt't 13, und the pinions F andiH thereon, with the lower rollers D E, and their respective pinions G and l, so that the sbnft extends underneath, the length of the rollers, and its pinions F and H gear respectively into the pinious G and I, al;v opposite ends of the rollers, thereby toenablethe rollers to be loc-.tted close together, for the purpose herein specified.

2, In combination with the above, the arrangement of the bagnsse-cnrrier, so that its belt is' driven by t-he pinion G, ol the rear lower roller' G, by means of two pinions n and o, around the shaftof which. latter the carrier turns furadjustment, thereby bringing the specified.

The above specification of' our improved mill for crushing and expressing the jn'ce from sorghum mld sugar-cane stalks, signed by us, this 21st dny of Februm-y, 1866.
